1 General Description
The FMC B479 SCU PK CGEA 1.3 key is remote unit with Transponder, PASE and Remote
Keyless Entry functionality. The transponder function is based on the Immo frontend inside
the microcontroller and one of the external LF coils. The PASE function is part of the PEPS
protocol (Passive Entry and Passive Start) that provides enhanced customer convenience
and security via a customer carried, passively or actively enabled Passive Key (PK)
communicating with the vehicle through an RF Receiver (RFM) to the BCM with an integrated
PEPS microcontroller.

2 Main components
2.1 UHF-Transmitter Token
The Token NCF29A1 is an extremely single chip solution that incorporates a Security
Transponder, UHF Transmitter RISC controller on the same chip. The device provides a fully
integrated fractional-N phase locked loop (PLL) frequency synthesizer and a power amplifier
to drive an external antenna. The Token is especially designed for use in the ISM frequency
bands.
2.2 Microcontroller
FXLS8962AF
The FXLS8962AF is a compact 3-axis MEMS accelerometer designed for use in a wide
range of automotive (convenience and security), industrial, and medical IOT applications that
require ultra-low-power wake-up on motion.
FXLS8962AF is available in a 2 mm x 2 mm x 0.95 mm 10-pin DFN package with 0.4 mm
pitch and wettable flanks. The device is qualified to AEC-Q100 and operates over the
extended –40 °C to +105 °C temperature range.
The combination of sensor performance, system power-saving features and extended
overtemperature-range performance makes FXLS8962AF an ideal accelerometer for motion
sensing in the automotive industry.
3 Functionality
3.1 Remote keyless entry
- Lock, Unlock, Trunk unlock
- Generating and transmitting an RF bit stream for remote entry functions
3.2 Transponder Start authentication
Communicating bi-directionally, LF/LF for authentication / remobilization if keyless vehicle
not work due to flat battery
.

3.3 Passive Entry and Passive Start
3.3.1 Passive Entry
Passive entry process is the authentication of the PK and BCM to enable unlocking
and locking of the vehicle among other functions requiring a PK search on the
interior of the vehicle.
The vehicle can be unlocked or locked as follows:
- Trunk open function: PK shall be on the outside rear of the vehicle
- Trunk close: No PK inside the trunk OR if there is a PK inside the trunk, the vehicle
shall not be in the armed state.
- Right side entry/locking: PK shall be on the outside right of the vehicle
- Left side entry/locking: PK shall be on the outside left of the vehicle
3.3.2 Passive Start
The Passive Start process is the authentication of the PK and the BCM for enabling
the power pack.
For the Passive Entry Passive Start, key authorization time must be less than or
equal to 285ms from the initial customer start command to sending the authorization
to the BCM
3.4 Mechanical key
Key blade is inside the key.
3.5 Remote Keyless Entry function
When a button is pressed, the microcontroller wakes up and calculates a unique telegram,
which is sent to the vehicle by modulating an RF oscillator. The telegram contains the
information, which button is pressed.
After transmitting (buttons released) the key returns into sleep mode to save battery power.
3.6 Transponder function
The transponder function is part of the immobilizer system and allows authenticating the key
and starting the engine independent from the key battery voltage level.
For that the key will be inserted in the ignition lock with immobilizer base station. The
immobilizer base station will charge the transponder with an LF field and send an
authentication request. After having received sufficient energy the transponder will answer
the request. This is recognized by the immobilizer base station and decoded. If the data
stream transmitted by the transponder fits to the expected data stream the immobilizer base
station will send a start engine message to the engine control.

4 Test Modes
The samples with test-software are marked with label "CW-mode". The keys with applications
software are marked with label “Application mode” or “App mode”.
The test-software allows setting the key in CW-mode for around 2 minutes. The testsoftware
operations are described in “Functional description of test setup” document.
